Pretty but comes up small

Very very small. The age 10 is too small for my tall 7 year old, will try the age 12 next. In reality age 10 should have fit with plenty of room. My daughter loves it, she love s the skirt and the pattern

Dětské plavky.

Plavky jsou moc hezké, proto jsem dceři koupila o dvě čísla větší velikost, ať je má na výrost, avšak velikost neodpovídá, má je těsné a odmítla je díky tomu nosit, bohužel jsem aktivně ustřihla štítek a tudíž je nemohla vrátit, ačkoli jsou nenošené. S dalším zakoupeným zbožím, jako jsou například běžecké boty jsem maximálně spokojená.

Your practice

Beginners swim: young beginner swimmers who are starting to swim and need ease and comfort. For her, Nabaiji offers a wide range of swimwear that allow her to swim with products suited to swimming, but that also meet anatomical requirements


X-shaped cross back: a swimsuit should focus above all on comfort, to allow you to perform your movements in complete comfort, without getting in your way or hurting you. That is why it is important to choose the cut of the back of your swimsuit carefully. In X-shaped-back swimwear, cross straps allow good freedom of movement. As the straps are not fixed together, they adapt to all body types.


Material: 80% polyamide / 20% spandex. Chlorinated water can be harmful to swimsuits that are used repeatedly in swimming pools. The spandex fiber that gives the material its stretch and therefore makes it comfortable, also becomes fragile when in contact with chlorine. If you swim occasionally, this material will be fine for you. If you swim regularly or intensively, opt for a 100% polyester material.

Restriction on use

Not recommended for use on slides.

Score to compare the environmental impact of products

The environmental impact of the product is calculated over its entire lifecycle and with different indicators. An overall score (ABCDE) is attributed to help you easily identify the products with the best environmental performance by comparing products of the same type with one another (T-shirts, pants, backpacks, etc.). Decathlon chose to apply this voluntary environmental labeling system. For more information, visit:
